The OCRECOM’s OQQS3414L is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for 30km optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of LAN-WDM optical signals, and multiplexes them into a single channel for 400Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 400Gb/s optical input into 4 channels of WDM optical signals, and converts them to 8 channels of 50Gb/s (PAM4) electrical output data.
